Greg Mankiw, Harvard economics professor and adviser to Mitt Romney, posts a chart on his blog showing the ratio between the pay of a worker and the pay/compensation of the CEO's at top 350 firms. (I assume the workers are the workers at the same firms, but whether it's mean or median or what, it's not clear--Prof Mankiw gets a "C" for copying the graph and failing to specify in his post.)
The professor seems must struck by the recent drop in CEO compensation--the ratio in 2000 was twice that in 2011. I'm more struck though by the increase, the ratio has increased 10 times between 1965 and 2011. In the good old days just after George Romney had left his CEO job at American Motors CEO's got roughly 20 times the compensation of their employees, say $100,000 to $5,000; in the bad new days when his son is running for President CEO's in big companies make 209 times the compensation of employees.
